Combine
Combine analysis combines the multiple input rasters, and outputs the combination of cells after performing statistics. That is, based on the combination of the cells of the two input rasters, the system will generate a unique value for the corresponding cell in the output raster, by which the change and quantity difference can be presented. If a cell contains NoData in any of the input rasters, NoData will be assigned for the corresponding cell in the output raster.
See the figure below:
1.Sort the changes of each cell value of the input rasters, please see the table below.
2.Output raster based on the sorting result(the same value change will be assigned the same value; for instance, two cells have the same change, 0(IR1) and 0(IR2), and the output value will be assigned 2 based on the sorting table).
3.If any one input cell has value NoData, that location will be assigned NoData on the output.
